Color vision deficiency (CVD) affects approximately 200 million people worldwide, compromising the ability of these individuals to effectively perform color and visualization-related tasks. This has a ...

Dichromacy occurs when a person can only see two colors due to only having two working types of cone cells. They cannot see one part of the light spectrum. Different types of dichromacy can develop.

That's called 'anomalous trichromacy'. And some of us have two cones only, called 'dichromacy'. These conditions are more colloquially called 'colour-blindness'.

The scientific terms are dichromacy (a type of color deficiency where one cone cell is completely absent – for example, if the green cone cell is absent, it is called Deuteranopia) and anomalous ...

Some individuals are missing a set of cones entirely (dichromacy) – these people see around one per cent of the colour those with normal vision do.

Several image recoloring methods have been proposed to compensate for the loss of contrast caused by color vision deficiency (CVD). However, these methods only work for dichromacy (a case in which one ...

There’s nothing magical about tricromacy, either. Up until now, that’s what has worked best for humans, but dichromacy can be found in about 8 percent of men and 0.5 percent of women.

Tritanomaly is reduced blue colour sensitivity, which is rarer Dichromacy is when one of the light cones don't work, leading to no sensitivity for a certain light spectrum, e.g. no red or green at all ...
